Help with EZNEC- Hey Roy!
 

FYI, Roy will be at the Friedrichshafen hamfest in Germany next week, so
he may already be traveling.

Like most travelers, he may have access to e-mail, but is unlikely to
have a newsgroup feed.

Actually they could have gain that low and still be directional.

Heck, I bet someone here may have even done something like it for some
reasonable engineering design.

If Fractus is the Fractal antenna business then it is still doing
well.
That was another antenna that amateurs tried to remove from the
face of the earth because it provided a new aproach to antennas.
Seems like professionals in the antenna industry are not made
from the same mold as the self styled amateur experts that
deride the new from their couch as they slowly pass away.
When they become silent keys any lock that they may have had
on the new decays in lock step with their gutless frames

Hi Arthur,

Your soap box would carry more weight if you actually contributed to
the design.

My point is that it is not "gone and long forgotten" despite
the venom from you and Roy in you attempts to devalue the idea.
Here we are twenty years on and the antenna survives as a
new technology. Just shows that you can't stop science when
the shrill of your voices runs out of puff. Fractal antennas
are now in the books signifying that the efforts of you and Roy
was all for naught and could not overcome the test of time.
Now your efforts are concentrated anew where again you will fail
despite the shrillness of your wailing. Ideas are for the books
and your venom doesn't count for inclusion.

Gee. I wonder if he will comment on the state of education in Germany
relative to his own American education. He may well be returning
now by swimming the pond in desparation.

Hi Arthur,

Unfortunately you don't understand the technology, so you lack the
authority to make this anything more than a sentimental statement.

My website contains more than 300 pages of results from real Fractal
antennas and it remains the largest website in the world devoted to
that topic alone. It even supports examples of fractal designs that
you couldn't beat.

Care to compare examples? Mine will be far more length efficient than
anything you could offer. They will be non-planar. They will offer a
better turning radius than yours.

No, comparison would quickly reveal all this and thus I will leave you
with the last gasping denial. ;-)

Try this (with Eznec 5)

Step 1 Open (or write) your file.
Step 2 Do farfield plot , then save
this file as (Tracefile (.pdf,pdf3)
You need to name this file!.

Step 3 Do the SAME steps for Antenna #2 (and 3,4,5, ect) be sure to use
diff names!

Now, Step 4,go to (view, traceview), and this

will give a warning.Run , under the "traceview window, the FIRST FILE you
named.

Step 5 Now , click on "Add trace". insert the name of
the SECOND file you saved ( Warning- both must be in
SAME direction, AZMATH, or ELEVATION for this to overlay) , and both ants
pointing the SAME WAY!

Step 6 either print it, or add another file .
Think you find this works pretty well .
NOTE: this DOESN'T set the max gain to BOTH
antennas, but is great for comparison purposes.

Ok, thanks Jim, I have done this and add a trace does just
that, but as you say,
"this DOESN'T set the max gain to BOTH antennas"
I want to equalize the max gain, So it looks like the copy to
Paint and compare there is the best solution so far.
Thanks, Mike

Do you think I didn't realise what direction you was heading?
Look at mine not at his!
I remember after you did that work you turned on Chip and
everything he had to say. Heck it then got worse when the
group found out that he was jewish. That was mana for the
group and finally got the job done to get rid of him.
No matter how much shame you feel that will be part of
you forever. Can you remember the last time you said
something nice? That should take a week or so to think about.
You are such a miserable person, always pushing good aside
for the benefit of evil.If your page is the only thing
you can point to as to what you have achieved in the
last twenty years you are indeed in a sorry state.

Noted and understood. Its national 'flag" day is it not?
With respect to EZNEC. MANA is much more ambedextrous than
Eznec. It does provide all the old stuff that eznec does
but it also supplies what is new from the last decade.
When you model using optimisation where the program
predetermines direction to take it opens up a whole
new world with respect to antenna design.
Ofcourse even optimisation is not new to antennas
which is why the program is offered for free to
amateurs. There is also a newsgroup based on MANA
so there is no need to search the amateur newsgroups
for the author to report bugs.
I don't think eznec can match it in any way, even
with the allowable number of segments used let
alone the number of variables available. If you
want to design an antenna that is in equilibrium
so that focussed radiation is denied it is just
one type of antenna design that cannot be met
using eznec. A lot of time has passed by since
eznec came on the scene as well as many changes
and additions with respect to antenna programs
so why impede your antenna learning by using
old technology? It certainly cannot be the cost.
